Title: Improvements in Appliances for Scaling Combustion Chambers of Boilers, or the like
Inventor: DRAKE EDWARD VIVIAN LANCE
Filed: 1906-12-11
Granted: 1907-11-14
Abstract: 28,172. Drake, E. V. L. Dec. 11. Cleaning tubes.-A tool for cleaning scale from the plates of boiler combustion chambers, and for like purposes, consists of a holder 1 mounted on a suitable actuating-rod 14 and carrying a removable chisel or other scraper 2. A nut 5, slidably disposed within the holder 1, carries an adjustable rod 7 and is acted upon by a spring 10. A screw 11, working in a slot 12, serves to lock the rod 7 and prevent rotation of the nut 5. In use, the rod 7 presses against one plate of the chamber and keeps the tool up to its work on the opposite plate, as. shown in Fig. 4.

Title: Improvements in Electric Time Switches.
Inventor: THORPE WILFRED BERTRAM
Filed: 1906-12-12
Granted: 1907-10-24
Abstract: 28,369. Thorpe, W. B. Dec. 12. Switches.-A switch is operated in two directions by two solenoids successively energized at given times. Two solenoids i, j have a common core h, which actuates a switch arm g. A disk a rotated by a clock carries four rings b, b<1>, c, c<1> electrically connected. A movable arm d is connected to the ring b, and an arm e to the ring c, and the interval of time between which these arms come into contact with the fixed contact f may be varied. The ring b<1> is connected to a brush k ; when this brush is on the contact k<1> and the arm d in contact with the fixed contact f, the solenoid i is energized and the core h pulled down, operating the main switch and cutting out the solenoid i. When the arm e makes contact with the contact f, the solenoid j is energized, the main switch is operated, and the solenoid cut out. According to the Provisional Specification, the hands may be independent of the disk a, which is then provided with two contacts which engage with the arms.

Title: Improvements in Pneumatic Tools
Inventor: CLEMENT JOHN FRANKLIN
Filed: 1907-01-24
Granted: 1908-01-24
Abstract: 1805. Clement, J. F., and Macneir, E. Jan. 24. Percussive handtools.-The handle of a pneumatic riveting &c. tool is fixed to the casing by a screw coupling 8, which coacts with a flange 11 and filler 10. The main distributing- valve has differential areas 30, 31, and is hollow to receive auxiliary valves 39, 40. The valve 39 has a reduced stem 39, which contacts with the end of the piston 34 and has recesses 42, so that the piston on its rearward stroke may be cushioned by live air from the groove 35 instead of by exhaust air ; grooves in its seating 43 also serve the same purpose. The valve 40 has an enlarged head 45 and contains passages 47, which are normally out of contact but which, in case the main valve stick, on starting the tool, are moved by impact with the valve 39 into communication with passages 48, so as to exhaust from the back of the valve into the groove 36 and port 64, Fig. 4. When the main valve is in the position seen in Figs. 1 and 4, air from the inlet port 27 passes into the groove 35, and thence into the port 50 to the space in front of the piston, which is returned, exhaust from the rear end passing through ports 57, 58 ; the port 58 is of smaller area than the port 57, so as to avoid cushioning by dead air, ports 56, 59, groove 36, and port 64. During the rearward stroke, air enters the chamber 38 through the port 49 to keep the valve 39 pressed to the left ; when the end of the passage 60 is uncovered, air passes through it and a port at its rear end to keep the main valve in its forward position. When the piston strikes the valve stem 39, the live cushioning-air drives back the main valve. Air then passes from the port 28 in front of the valve, Fig. 3, and drives out the piston, exhaust from the other end passing through passages 63, 55, groove 36, and port 64. When the rear of the piston uncovers a port (not shown) in the passage 60, air passes through it to drive forward the main valve, when air passing through the groove 35 and port 49 moves forward the valve 39.

Patent GB-190708797-A (GB)
Title: Improvements in Rotary Engines.
Inventor: KETLEY CHARLES BOSWORTH
Filed: 1907-04-16
Granted: 1908-04-16
Abstract: 8797. Ketley, C. B., [McLellan, H. R.]. April 16. Revolving-cylinder type.-Four cylinders C, Figs. 3 and 4, of square or rectangular section, contain oscillating pistons G made with expansible packing. The pistons are pivotally connected to a pin H, normally fixed. One side of the cylinders is formed of a plate carrying a sleeve c, suitably packed, which embraces a cylinder F, normally fixed. The other side of the cylinders consists of a plate D, containing various steam distribution passages, formed integrally with a trunnion b secured to the driving-shaft B. The distributing-valves consist of four piston valves k, Fig. 6, arranged in casings I. Opposite valves are connected by yokes m, of the shape shown in Fig. 10. The broad part of each yoke engages an eccentric n formed integrally with the steam-chest J, Fig. 3. The pin H is secured in a boss h formed in the interior of the cylinder F. The operation of the engine is as follows :-Steam passes from the supply pipe q to the steam-chest J, and thence through suitable ports to longitudinal passages in the trunnion b; it then passes by way of radial passages in the plate D to ports o, Fig. 6, and into the valve casings. As the ports j, Fig. 6, are uncovered, steam enters the cylinder, and owing to the eccentricity of the pin H a torque is produced and the cylinders rotated. On the return stroke of each piston the steam is exhausted through the port j, whence it passes to a port, which has in the meantime been uncovered by the valve, which forms a part of a radial passage s, formed in the plate D, and flows into the space u, Fig. 3, along the cylinder F, to the exhaust pipe. The cylinder F is arranged in bearings d, e so that the position of the pin H can be altered for reversing. A hand-lever is provided for shifting the cylinder F.

Title: Improvements in Starting Mechanism for Internal Combustion Engines.
Inventor: BELL JOHN DALRYMPLE
IPC: F02P1/00
Filed: 1908-05-29
Granted: 1908-12-17
Abstract: 11,670. Bell, J. D. May 29. Gas and like engines, starting. The ignition device, preferably a magneto, is connected to a shaft C driven by the engine, through epicyclic gearing arranged so that the rotation of the starting-handle first retards the ignition, then turns the engine to draw in and compress a charge, the ignition being so much retarded that the spark is produced in a cylinder in which no compressed charge exists; finally, a backward rotation of the starting-handle turns the magneto shaft A at a high speed-ratio into its normal position. The compressed charge is then ignited and the gear is automatically locked solid so that the shafts A and C rotate together. To facilitate compression, the gear can also be used to turn the engine at a reduced speed-ratio, at starting. The sun-pinion B is mounted on the magneto shaft, the planetpinion carrier D on the shaft C, and the internally toothed wheel F, provided with external helical teeth G<2>, can be driven by the wheel H connected to the starting-handle. A pin L, Fig. 3, fixed to a spring - pressed plate M, locks the wheel F to the planet-pinion carrier D at one or other end of a circular groove D'. To start the engine, the wheel H is brought into gear with the wheel F, pressing back the plate M so that the pin L can move in the groove D'. The wheel H is then turned forwards, driving the magneto backwards at a high speed ratio until the pin L reaches the end of the groove, as shown in dotted lines in Fig. 3 ; further movement of the starting-handle then turns the engine with the gearing locked solid. When a charge has been drawn in and compressed, the starting-handle is turned backwards, advancing the magneto at a high speed-ratio to its normal position and firing the charge. The backward rotation of the wheel H disengages the helical gear, and the pin L takes up the position shown in full lines, so that the gear is locked with the magneto in the position for normal running. If the engine stops with a partly compressed charge in one cylinder, a pawl R is moved into engagement with ratchet teeth P on the sunpinion, and forward rotation of the starting- handle turns the engine forward at a reduced speed-ratio until the pin L locks the gear. When battery ignition is used, the sun-pinion is connected to the contact-maker ; and when igniting by high compression, catalytic, or calorific devices, the sun-pinion is connected to the compressor or to the timing-valve.
